Things that don't make sense (v2)

Yeah, a lot of those conversations can make no sense either depending on who Shepard took on the squad.  I often can't remember who I took on individual missions so it took me awhile to notice that they said the same thing regardless of whether or not they had actually been taken on those mission.

I still think though that "joined up with Shepard" implies something different.  I do think the conversation in the elevator is a writing error... or maybe a coding one.  They might have intended to prevent that line from triggering during the first visit to the Citadel and just overlooked it when coding it.  There are other lines that trigger only after certain events... like the news report on Kohoku's death.

Another thing that doesn't make sense though... Shepard can ask Anderson about Kohoku after Kohoku's dead - Shepard will still just ask if Anderson knows where he can find him and Anderson will still say that he thinks he's in the tower asking about his men.  The first time I activated that option after just hearing about Kohoku's death in the elevator was rather confusing since I was expecting Shepard to tell Anderson about Kohoku's death instead of asking where he could find him.
